The upper chambers of the mammalian heart that receive blood returning from the venous circulation (right atrium) or from the lungs (left atrium).
paired upper heart chambers responsible for receiving blood returning to the heart from the body
plural of atrium. Blood is returned from the lungs, to the left atrium, from where it is pumped into the left ventricle and then round the body, or from the body, to the left atrium be pumped into the right ventricle and then to the lungs
plural of atrium. The left atrium pumps oxygenated blood into the left ventricle. The right atrium pumps deoxygenated blood into the right ventricle from where it is pumped into the left ventricle.
The plural form of atrium. see Atrium
Two chambers that form the curved top of the heart (right atrium and left atrium).
the heartâ€(tm)s two upper chambers. They receive blood from the lungs and body.
upper receiving chambers of the heart
The plural of atrium. The atria are the two smaller chambers of the heart. Each atrium consists of an open space with recessed walls. See the entire definition of Atria
The upper chambers of the heart that pump blood to the lower chambers (ventricles).
The top pair of heart chambers, which basically serve to serve blood to the main pumping chambers, the Ventricles.
The filling chambers of the heart, one on the right side and one on the left. Blood is collected in the atria while the ventricles are contracting. This blood is then released into the ventricles when they are ready to fill, see Figure 7.
upper cavities or chambers of the right and left sides of the heart; singular is "atrium"
The two upper chambers of the heart.
Two thin-walled chambers of the heart that pump blood into the ventricles; consists of right atrium and left atrium.
The top two chambers of the heart. A single chamber is called an atrium.
The upper chambers of the heart. (Atrium refers to one chamber of the heart)
the upper chambers of the heart, specifically the right atrium and left atrium. The atria collect blood as it comes into the heart and fill the lower chambers (ventricles) with blood.
The upper two chambers of the heart muscle that collect blood as it enters the heart and fill the lower chambers (ventricles) with blood. The atria are separated by a membranous wall known as the atrial septum. Singular: atrium.
The first chamber on either side of the heart which receives blood from the veins.
The upper two chambers of the heart, which receive blood before it flows to the ventricles. Back to Previous Page
The atria are the chambers of the heart which receive blood and pump it into the ventricles. There is a left atrium and a right atrium.
Thin-walled chambers of the heart that receive venous blood from the pulmonary or systemic circuit.
The left and right atria are two of the four chambers of the heart.
Upper two heart chambers. Right atria delivers blood to right ventricle. Left atria delivers blood to left ventricle.
(singular: atrium) Chambers of the heart into which blood returns from the body or lungs before passing into the ventricles.
The atria are the upper chambers of the heart that collect blood before passing it on to the ventricles (atrium singular). The right atrium is the upper right cardiac chamber that receives deoxygenated blood from the inferior and superior venae cavae and delivers blood to the right ventricle. The left atrium is the upper left cardiac chamber that receives oxygenated blood from the pulmonary veins and delivers blood to the left ventricle.
The upper chambers of the heart that receive blood from the veins and pass it to the lower chambers of the heart.
